Huawei Showcased Optical Transport Network Solutions at UBBF 2022

Huawei showcased multiple cutting-edge technologies of optical transport networks, demonstrating innovative service ideas and technical practices for global carriers.

As global digital services develop, optical private line services are widely used in various industries and scenarios. For example, the Virtual Teller Machine (VTM) remote customer service of banks guides customers of account opening; healthcare cloudification allows doctors to browse patient reports on the cloud; and the cloud rendering technology realizes sightseeing in the outer space at home.

Optical private lines with high bandwidth, low latency, and high reliability have gradually set off a trend and become a common need in business scenarios.

Although the development of private line services varies from region to region, how to monetize OTN private lines has always been a major concern of global carriers. To address this issue, Huawei equips iMaster NCE with innovative capabilities to improve the intelligence of optical networks and provide key monetization enablement for private line services.

As the technical core of the OTN network management and control system, Huawei iMaster NCE provides full-service-lifecycle support for carriers’ private line monetization.

It not only provides basic service provisioning and alarm monitoring functions, but also supports sales through ACTN NBIs, helping carriers improve efficiency and increase revenue.

In the private line sales expansion phase, carriers can quickly query the minimum latency of private lines based on the latency map from iMaster NCE, ensuring customers’ latency and bandwidth requirements are fully met and improving the service matching efficiency.

In addition, with the online visualization and automatic recommendation functions of private line availability, carriers can accurately filter for high-reliability private lines that meet the customer’s further requirements.

In the service provisioning phase, StellarGo, an innovative technology, implements customer SLA requirement satisfaction and improves the efficiency of OTN private line provisioning.

It trains a path calculation and recommendation model based on expert experience and massive data, which can implement multi-factor, multi-policy intelligent path selection instead of the single-factor, single-policy path selection in the past.

In addition, it provides personalized recommendations based on the SLA requirements of customers.

It has been verified that the path calculation success rate reaches 99% and the service provisioning efficiency is improved by 70%. With the help of better recommendation algorithms, customers can obtain higher-quality private line services.

In the service O&M phase, the private line SLA assurance capability helps carriers monitor key service performance indicators in real time so as to identify and avoid service SLA risks promptly. In the showcase, the latency of a Beijing-Shanghai (1200 km apart) private line is as low as 10 ms.

According to a customer, given that distance between Chiang Mai and Bangkok is about 800 km, OTN optical private lines can cover the entire territory of Thailand with networks of 10 ms latency, which can largely change the network capability.

In addition, Huawei’s reliability commitment also contributes to monetization of customers’ private lines.

By enabling ASON at the network layer, as well as intelligent incident management and fault forecast at the NMS layer, carriers can quickly identify root causes of faults, locate faults, and constantly provide highly reliable and zero-fault network services for their customers.

Huawei experts conclude that the digital development of various industries strongly requires the support of optical private lines and optical networks.

Improving automation and intelligence capabilities will be an essential step for carriers’ business success.

Huawei believes that through the collaboration and continuous exploration by all parties, the premium connection of optical networks will benefit various industries and become a cornerstone for rapid development in the digital era.
